UNITED STATES JOHN PETTIT, E BARTLESVILLE, oKLiirrc/lvra PUMP VALVE.

Application filed october 27, 1923, Serial No. l671,151.

To all whom t may concern:

Be it known that L'JOHN PETTIT, a cit-izen of the United States,residing at Bartlesville, in the county of Washington and State l ofOklahoma, have invented certain new and useful Improvements in PumpValves, of which the following is a specification'.

This invention relates t'o a valve mechanism employed in wells in whichsand and l0 the like is commingled with the fluid which is being pumped,and has for one of its objects to provide a simply constructedattachment whereby the sand and the like is prevented from settling'oraccumulating in the valve chambers or upon the valve packings,

or other parts, but will be constantly and au- Y tomatically agitatedand discharged with the fluid which is being pumped.

Another object of the invention is to pro- Vith these and other objectsin view the invention consists in certain' n-ovelvfeatures ofconstruction as hereinafter shownandl described and then specificallypointed out in the claims, and in the'drawings illustrative of thepreferred embodiment of the` invention- Figure 1 is a vertical sectionof the improved device.

Fig. 2 is an enlarged plan view'of the centering device for the tubularconductor member.

Fig. 3 is a plan view of the combined cou- 'pling and bottom of the sandchamber with the agitating tubes in position.

Fig. 4 is a side elevation, partly in section, of the parts shown lin'Fig. 3.;

In most oil wells, and the like, quantities et Saad. .are @reminded'with theiludand vide a device of this character in whichy being heavierthan oil, settle on the pump parts, and unless removed or dischargedwith the oil, seriously'damage the packings or cups on thework-ingvalves and rendering it necessary to pull the pump valves tor55 renewthe packing, at frequent intervals, which is a serious obstacle 'andasource of annoyance and expense.

With the improved attachment herein Y shown and described, the sand orthe like which may be commingled'with the fluid being pumped isconstantly and automatically agita-ted and thereby prevented fromsettling in the valve chambers or upon the valves 'or the packing, butis discharged with the flow through thepump. y

The improved device may be adapted to various forms or construction ofpumps, but for the purpose of illustration is shown applied to theoperating 'Valve portion of a conventional pump structure, comprising alower barrel member 10 having a wear lining member 11, the'm'embers 10and 11 being coupled to a lower'coupling ring 12, in which the upper endof the tubing anchor is 7. connected and represented at 13. 1 Threadedinto the coupling ring 12 is tubular wear or f lining member 16,` and'threaded upon the v upper end 'of the wear member is a guide sleeve 16and coupled' to the upper end of the lower barrel 10'is'a sleevel whichis closed at the upper end except for a rela tively large centralinternally threaded opening to receive the lower end of a tubu-` larmember 16, and a plurality of smaller openings encircling the largercentral opening. Y.

Coupled to the upperend'of the sleeve 15 is an upper barrel memberlS,the latter being coupled at its upper end by a collar 19 9o to the welltube, a portionof which is repre:

' sented at 20.

At its upper end the tube 16 is coupled to a perforated annularcentering member 21.

Fitting within each of the apertures of the member 15'is a relativelysmall tube 22, each of 'the tubes being turned over into `a half circlewith the discharge ends pointing downwardly, as shown in Figs'. 1 and 4.Any required number of the tubes 22 maybe 2511i threaded stud .indicatedat; 32 ato'.= receive l.the
